NM should recognise Motorola A1200 (phone in Modem mode) but it does not.

When connected via USB, the device is bound to /dev/ttyACM0 and I can succesfully connect to the Internet using wvdial.

[Jae Stutzman (jaebird)]

I have a Motorola E2 ROKR, which has the same lsusb output as reporter. It also does not work with Jaunty's NM. BTW, this worked fine under Intrepid with my setup.

[Chertykov Denis (chertykov)]

I have a bit more investigated the bug and found the following:

1. run udevadm control --log-priority=debug
2. plug the phone (A1200) to usb
3. look at syslog

Part of my syslog:

IMHO the problem is here: '/lib/udev/nm-modem-probe' (stderr) 'error

[Chertykov Denis (chertykov)]

udevadm control --log-priority=debug

[Alexander Sack (asac)]

please run

/lib/udev/nm-modem-probe --verbose --export on your /dev/ttyACM0 (and 1,2 etc)

and give us the output.

[Jae Stutzman (jaebird)]

This is my Motorola E2

related syslog snippet when connecting:

nm-system-settings: SCPlugin-Ifupdown: device added (udi: /org/freedesktop/Hal/devices/usb_device_22b8_3802_noserial_if0_serial_unknown_0, iface: (null)): iface not found
NetworkManager: <info> (ttyACM0): found serial port (udev: hal:GSM)
NetworkManager: <info> (ttyACM0): ignoring due to lack of probed mobile broadband capabilties

also a little spelling: "capabilities" :)

[Chertykov Denis (chertykov)]

I'm already trying nm-modem-probe and I think that it's work right.

[Chertykov Denis (chertykov)]

Also,
As I understand, this is a problem:
NetworkManager: <info> (ttyACM0): found serial port (udev: hal:GSM)

Must be (udev:GSM hal:GSM)

As I see the bug is not planned to be resolved :-(
Do you have any tips where its location and how to resolve? May be I try to see...

[Pedro Villavicencio (pedro)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release the Karmic Koala. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

[lexis (tikhvinsky)]

I have Ubuntu Karmic test branch installed at my laptop that is updated regularry. Is it enough to test on it instead of the Live CD?

[Stefan Nagy (stefan-nagy)]

I can confirm that this bug is still present in Karmic. I can use my Motorola A1200 as a modem with 'Gnome PPP' without any problems.

After connecting my Motorola A1200 I get this in syslog:

Apr 14 22:39:16 rosa kernel: [ 148.696068] usb 3-1: new full speed USB device using uhci_hcd and address 3

Seems like It has something to do with modem-manager, so I attach the a debug-log & add modemmanager to the affected packages. Please tell me if you need more information.

[Stefan Nagy (stefan-nagy)]

Nothing changed in Lucid.

Seems like modem-manager tries to send an AT-command which isn't supported by the Motorola A1200: 'ATI' - with which it tries to request identification information.

I sent the 'AT+CLAC'-command to the phone to get a list of all available AT commands. I attach this list - maybe it helps...

[hector (mailbox-deandreis)]

I,ve the same problem on kubuntu 10.04. the same syslog
At this moment the modem "don't work" also with kppp.

[Dan Williams (dcbw)]

This should be long fixed in ModemManager 0.4 or later; I just tried a ROKR E2 and it's correctly detected as a GSM phone. It has been fixed since:

commit b1992f903b27f2a0b8190daaedcbe76790180c3c
Date: Mon Jan 18 23:22:02 2010 -0800

If you need further debugging, do the following:

mv /usr/sbin/modem-manager /
killall -TERM modem-manager
modem-manager --debug
<plug in your phone and wait for it to fail>
Ctl+C to kill modem-manager
mv /modem-manager /usr/sbin/

and then get the debug logs from MM, then post them to http://bugzilla.gnome.org .
